Answer 2

Answer : The correct option is, (4) 0.01 M $K_2SO_4$

Explanation :

Specific conductance : It measure the ability of that material to conduct electricity. It is represented by the symbol 'k'.

The specific conductance of electrolytic solutions depends on many factors:

The depends on the nature and the concentration of the electrolyte added.

The depends on the size of the ions produced.

The depends on the temperature.

(1) The dissociation of $CH_3COOH$ will be :

$CH_3COOH\rightarrow CH_3COO^-+H^+$

The number of ions = 2

(2) The dissociation of $NH_4OH$ will be :

$NH_4OH\rightarrow NH_4^++OH^-$

The number of ions = 2

(3) The dissociation of $NaCl$ will be :

$NaCl\rightarrow Na^++Cl^-$

The number of ions = 2

(4) The dissociation of $K_2SO_4$ will be :

$K_2SO_4\rightarrow 2K^++SO_4^{2-}$

The number of ions = 3

As per given in the question, all the electrolyte have the same concentration. So, the specific conductance depends on the dissociation nature of an electrolyte into respective ions in the solution. The more the number of ions, the highest will be the specific conductance. So, 0.01 M $K_2SO_4$ solution has the highest specific conductance.

Hence, the correct option is, (4) 0.01 M $K_2SO_4$
